Korean romanization system

ABSTRACT

An unambiguous romanization system is provided. A look-up table having a unique and unambiguous correspondence between individual characters of Korean language having Korean language vowels and Korean language consonants, and syllables of English language having English language vowels and English language consonants is implemented into the computerized romanization system. The table is constructed to assure phonetic fidelity between pronunciation of the individual syllables of Korean language and the syllables of English syllables of English language. The system includes a key board, a microprocessor coupled to the key board and receives syllables of English language, a first memory connected to the processor and having the look-up table storing the correspondence, and the microprocessor converting syllables of English language into syllables of Korean language or converting syllables of Korean language inot syllables of English language with the uniqueness, the unambiguity, and the phonetic fidelity.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a romanization system allowing no ambiguity for both romanization and reverse transliteration processes of Korean language and providing the closest phonetic similarity between Korean characters of the Korean language and corresponding English alphabet renditions, and more particularly, to a romanization system implemented into a computer for converting English syllables into Korean syllables and the Korean syllables into the English syllables with unambiguity and phonetic fidelity.

[0003] 2. Description of the Prior Art

[0004] A foreign language is traditionally or typically romanized based on a phonetic way of how it is pronounced without regard to how it is spelled in the native language with only secondary consideration on the spelling. The McCune-Reischauer (M-R) system introduced in 1939 and currently used by U.S. government agencies is an example of the phonetic romanization system. According to the M-R system, a given Korean syllable can be transliterated into several different Latin language expressions depending on sound variations. Since the pronunciation of the given syllables of the Korean language varies from person to person and from one Korean province to another, the romanization of the given Korean syllables of the Korean language transliterated by the M-R system is complicated and difficult. Moreover, a reverse transliteration of the M-R system is ambiguous since the romanized Latin character is identified with not just one but several different syllables of Korean consonants and Korean vowels. Furthermore, another shortcoming of the M-R system is that there are no well established rules for using a space and a hyphen to discriminate each of serial groups of Korean syllables of the Korean language from others of the serial groups of Korean syllables of the Korean language containing the same characters of consonants and vowels. There are additional ambiguities caused by many different ways of implementing diacritical symbols under the M-R system. Therefore, the M-R system is in inconsistences that can create even greater number of variations in romanizing the serial groups of the Korean syllables of given Korean words or names.

[0005] For example, a Korean geographical name “

” can be romanized by the M-R system in at least 192 different ways, such as P'onganbuk-to, P′{haeck over (y)}nganbuk-to, P'yong'anbuk-to, P'{haeck over (y)}ng′anbuk-to, P'yongan-bukto, Pyongan Puk-to, Pyongan-buk To, Pyongan Pukto, Pyonganbuk-To, and Pyongan-bukto. These variations are due to the combination of the following three different effects: Korean consonants and vowels of the Korean Language romanized into different syllables of the Latin language; lack of discrimination between each of serial groups of syllables from others of serial groups of syllables containing the same Korean consonants and vowels; the M-R system employing diacritics in many different ways of romanized syllables which contain identical constituent Korean consonants and vowels.

[0006] Since the given original Korean syllable of Korean language is identified with the several different syllables of the Latin language, the information about the original Korean spelling would be lost during the romanization process. Therefore, the M-R system is not suited for computer data search and retrieval. Search for the original given Korean syllables is extremely difficult because a user has difficulties guessing in what romanized syllables of the Korean word or name were originally entered into the computer apparatus. Moreover, automatic transliteration of the M-R system is impossible in the computer because hundreds of pronunciation rules should be incorporated into transliteration software programmed in the computer and because many of the rules governing the use of the M-R system are variable and subjective.

[0007] According to traditional Korean romanization or transliteration systems, characters of Korean language are romanized into characters of English language by using a table showing a correspondence between the characters of Korean language and the characters of the English language as shown in a plurality of romanization tables of a Korean-English Dictionary published by Martin et al. which is available on an Internet site at http://www.sungwh.freeserve.co.uk/flux/korean.htm. These conventional systems, however, do not assure phonetic fidelity between pronunciation of the individual syllables of Korean language and the syllables of English language. An English syllabic consonant or vowel does not represent the same pronunciation as the corresponding Korean syllabic consonant or vowel.

[0008] Moreover, the conventional systems show ambiguity between the syllables of English language and the corresponding syllables of Korean language because the individual syllables of Korean are romanized into a plurality of several different syllables of English language and because the syllables of English language are assigned to a plurality of several different individual syllables of Korean language. Since the correspondence between the syllables of English language and the corresponding syllables of Korean language shows the ambiguity and lacks the phonetic fidelity, the conventional transliteration table can not be automated with a computer system for automatically converting the syllables of Korea language into the syllables of English language.

SUMMARY OF THE INVENTION

[0009] It is an object of the present invention to provide a romanization system able to provide a unique and unambiguous correspondence between individual syllables of Korean language and syllables of English language.

[0010] It is another object of the present invention to provide a romanization system implemented into a computer for automatically converting syllables of Korean language into syllables of English language or syllables of English language into syllables of Korean language.

[0011] It is still object to provide a romanization system capable of assuring phonetic fidelity between individual syllables of Korean language and syllables of English language.

[0012] It is further object to provide a romanization system able to prevent syllables of English language from being converted into more than two different syllables of Korean language.

[0013] It is also an object to provide a romanization system able to separate each of the syllables of the romanized word by a space so that the romanized word can be converted back to individual syllables of Korean language without ambiguity.

[0014] These and other objects may be achieved by providing a computerized romanization system including a keyboard having a plurality of keys each representing a different English language character, a memory having a lookup table showing a unique and unambiguous correspondence between individual Korean language vowels and Korean language consonants, and English language vowels and English language consonants, with the table being constructed to assure phonetic fidelity between pronunciation of the individual Korean language characters and the corresponding English characters, a microprocessor connected to the keyboard and the memory, and a display device.

[0015] This invention contemplates a Korean language input method where the microprocessor receives through the key board, a source passage of serial groups of one or more keystrokes of the English language characters with each of the group comprising selected syllables of English language, the microprocessor automatically converting each of the serial groups of English language characters into a destination passage in Korean language having the individual syllables of Korean language in accordance with the look-up table, and a video display device providing a visual display of the destination passage containing the individual syllables of Korean language. The microprocessor receives through the keyboard a “source” passage of English syllables, which represent Korean syllables. Upon the user's command, the microprocessor converts the English syllables into a “destination” passage comprising the Korean syllables equivalent to the source passage in accordance with the look-up table. When the English syllables characters corresponding to the individual syllables of Korean language are typed in the computer system and followed by a space keystroke, the English characters are automatically converted into the corresponding individual syllables of Korean language. A video display device provides a visual display of the source passage first, which is then replaced by the destination passage after the conversion takes place.

[0016] This invention also contemplates machine transliteration software to be implemented into a computerized system having a microprocessor and a look-up table. Serial groups of Korean syllables, such as one created by a Korean word-processor that are contained in the memory and displayed on the screen, are automatically converted into the corresponding serial groups of English syllables in accordance with the look-up table.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Returning now to the drawings, the related art shown in FIG. 1 illustrates a table showing each assignment between English language alphabet and Korean language consonants and vowels which are described in the McCune-Reischauer system which is the United States government standard. FIGS. 2A and 2B show ambiguous conversions between syllables of English language and syllables of Korean language.

[0030] According to FIG. 1, English language alphabet is assigned to each of Korean language consonants as follows. For examples, “K or G” is assigned to “

”; “T or D” to “

”; “P or B” to “

”; “S or SH” to “

”; “CH or J” to “

”; “CH or CH′” to “

”; “K or K′”to “

”; “T or T′” to “

”; “P or P′” to “

”.

[0031] “K” is converted into two different Korean language consonants “

” and “

” while “CH” is converted into two different Korean language consonants “

” and “

”, Moreover, “P” is converted into a Korean language consonant “

” or “

.”

[0032] As shown in FIGS. 2A and 2B, syllables of English language romanized from syllables of Korean language “

” or “

” might be converted into several different syllables of Korean language each different from the original syllables of Korean language if the syllables of English language is converted into syllables of Korean language based on the table of FIG. 1. As shown in FIG. 2B, the Korean word “

” can be transliterated inot many different ways. Also, reverse transliteration of one of the romanizations yields several different Korean expressions.

[0033]FIG. 3 is a table showing Korean language consonants and English language alphabet assigned to each of Korean consonants constructed by the principle of the present invention. For example, Korean consonant “

”, “

”, “

”, “

”, “

”, “

” and “

” are romanized into G, B, J, CH, K, T, and P, respectively. Only one Korean language consonant is assigned to only unique English alphabet of which pronunciation is closest to the corresponding Korean language consonant. An initial Korean language consonant “

” of syllables of Korean language is converted to “R” while a final Korean language consonant “

” of syllables of Korean language is romanized to “L”.

[0034]FIG. 4 is a table showing Korean language vowels and English language alphabet assigned to each of Korean language vowels. For example, the Korean vowels “

”, “

”, “

”, and “

” are assigned to “U”, “O”, “OO”, and “YOO”, respectively.

[0035]FIGS. 5A and 5B illustrate an input method of the present invention for converting syllables of English language into syllables of Korean language, showing a unique and unambiguous correspondence between individual syllables of Korean language and syllables of English language. No ambiguity exists between Korean language consonants and vowels and English language alphabet assigned to each of Korean language consonants and vowels. Each of syllables of English language is converted into a unique syllable of Korean language.

[0036] When “MI” of English syllables is followed by a space key stroke, then “MI” is converted into “

” which appears on a screen in a place where MI is displaced. If “GOOG” of English syllables is input, “GOOG” is displayed adjacent to “

”, the converted Korean syllable. “GOOG” of English syllables is converted into “

” of Korean syllables when a space key stroke follows “GOOG.” “

” of the Korean syllables means the United States of America. For the transliteration of “

” of Korean syllables, “TEUG” of English syllables is followed by a space key stroke, then “TEUG” is converted into “

” which is shown on the screen. If “HU” of English syllables is input, “HU” is displayed on the screen adjacent to of the converted Korean syllables. “HU” of English syllables is converted into “

” of Korean syllables when a space key stroke follows “HU.” The next syllables “CHUNG” is displayed on the screen adjacent to “

” of the converted Korean syllables. By the space key stroke, “CHUNG” of English syllables is converted into “

” of Korean syllables, and the transliteration of “TEUG HU CHUNG” is completed as shown in FIG. 5B. Each of the English syllables is distinguished by the space key stroke from others of the English syllables. FIGS. 5A and 5B illustrates complete unambiguity during conversion from the Korean syllables to the English syllables because of the unique and unambiguous correspondence between each of Korean syllables and each of English syllables and because of the space key stroke distinguishing each of English syllables.

[0037] A schematic block diagram of FIG. 6 shows a computerized romanization system for converting between Korean language consonants and vowels and English language alphabet based on the tables of FIGS. 3 and 4. The system includes a key board 10 containing a plurality of keys each representing a different English language character, a microprocessor 20 coupled to key board 10 and receiving a source passage including serial groups of one or more keystrokes of English language characters and automatically converting the source passage into a destination passage in Korean language having the individual syllables of Korean language in response to a space key stroke input from key board 10, a memory 30 connected to microprocessor 20 and having a lookup table 31 storing a unique and unambiguous correspondence between individual syllables of Korean language having Korean language vowels and Korean language consonants, and syllables of English language having English language vowels and English language consonants, with the table being constructed to assure phonetic fidelity between pronunciation of the said individual syllables of Korean language and the syllables of English syllables of English language.

[0038] A video display device 50 is connected to microprocessor 20 and displaying on a screen any combination of the correspondence stored in the lookup table 31, the source passage, and the destination passage. A printer 60 is connected to microprocessor 20 able to print either the source passage or the destination passage as desired.

[0039] Based on the tables shown in FIGS. 3 and 4, the syllables to be converted are input to microprocessor 20 by a user through keyboard 10. For example, if the user wants to input syllables of Korean language “

”, the user inputs MI, space key, GOOG, space key, TEUG, space key, HU, space key, CHUNG, and space key. Whenever the space key is input through key board 10 to microprocessor 20, English syllables separated by spaces are converted into corresponding Korean syllables.

[0040] If a passage of serial groups of English language “MI GOOG TEUG HU CUNG” or Korean language “

” is stored in memory 30 or transmitted from an external source through microprocessor 20 and stored in memory 30, the passage can be automatically converted into the corresponding Korean syllables or the corresponding English syllables, respectively. For example, during the input process, each of syllables, MI, GOOG, TEUG, HU, and CHUNG is converted to syllables of Korean language in accordance with the correspondence stored in look-up table 31 if a space exists between the syllables, such as MI and GOOG, GOOG and TEUG, TEUG and HU, and HU and CHUNG. MI is automatically converted into “

”; GOOG is automatically converted into “

”; TEUG is automatically converted into “

”; HU is automatically converted into “

”; CHUNG is automatically converted into “

”.

[0041]FIGS. 7A through 7F illustrates a visual display displaying the input process for converting English syllables into Korean syllables according to the input method of FIG. 5. If the user inputs English language alphabet TEUG and a space indicated by a manual depression of a space bar provided by keyboard 10, TEUG of the English syllables is automatically converted into syllables of the Korean language “

”. If the user inputs HU, a space, CHUNG, and a space in sequence, HU and CHUNG are automatically converted into “

” thereby sequentially showing “

”. Depending on the system, a space may exist between syllables of Korean language. The converted syllables of Korean language may be stored in memory 30 and displayed on the screen of video display device 50 as shown in FIGS. 7A through 7F.

[0042]FIGS. 8A through 8F shows a visual display displaying the transliteration between a Korean passage having serial groups of Korean syllables and an English passage having serial groups of English syllables. When the Korean passage stored in memory 30 or transmitted from the external source is displayed on the screen of video display device 50, the user may highlight a portion of the Korean passage to be transliterated as shown in FIG. 8B. The only highlighted portion “

” out of the Korean passage “

” is transliterated into English syllables in response to a transliteration key, such as a space key or a designated key, input from keyboard 10, and the transliterated portion is displayed on a portion of the screen. In FIG. 8E, a portion “TEUG KU CHUNG” out of “MI GOOG TEUG HU CHUNG” is highlighted and transliterated into Korean syllables.

[0043]FIG. 9 shows a flow chart showing the input method for converting syllables of English language into individual syllables of Korean language. Key strokes of English language are input to microprocessor 20 through keyboard 10 in step 910, and syllables of the English language corresponding to the key strokes are displayed on video display device 50 in step 920 and stored in memory 30 in step 930. In response to a space key in step 935, the input key strokes of English language letters form an English syllable in step 936. The English syllable is converted into syllable of Korean language in step 940 based on the tables shown in FIGS. 3 and 4. The converted syllables of Korean language are displayed on video display device 50 in step 950, and stored in memory 30 in step 960. Depending on the user's input of next English syllables to be converted into Korean syllables, the steps 910 through 960 repeat.

[0044]FIG. 10 shows an English-Korean automatic transliteration system. Key strokes of English language for the English passage are input to microprocessor 20 through keyboard 10, or the English passage is stored in memory 30 or transmitted from an external source and stored in memory 30 in step 1010. The English passage is displayed on video display device 50 in step 1020 and stored in memory 30 in step 1130. In step 1036, the user selects portions or all of serial groups of syllables of the English language which the user wants to convert into syllables of Korean language. In response to a transliteration key input in step 1037, each of serial groups of English language is converted into each of syllables of Korean language in step 1040 based on the tables shown in FIGS. 3 and 4. The converted each of syllables of Korean language is displayed on video display device 50 in step 1050 and stored in memory 30 in step 1060.

[0045]FIG. 11 shows a Koren-English automatic transliteration system for automatically converting a Korean passage of serial groups of syllables of Korean language into individual syllables of English language. Key strokes of Korean language for the Korean passage are input to microprocessor 20 through keyboard 10, or the Korean passage is received from an external source in step 1110. The Korean passage is displayed on video display device 50 in step 1120 and stored in memory 30. In step 1130, the user selects portions of serial groups of syllables of the English language which the user wants to convert into syllables of Korean language. When the user clicks the transliteration key or the space key in step 1137, the selected portions of serial groups of the syllables of Korean language are transliterated into each of serial groups of Korean language in step 1140 based on the tables. The converted syllables of English language is displayed on video display device 50 in step 1150 as shown in FIGS. 8D through 8E and stored in memory 30 in step 1160.

[0046] As described above, the computerized romanizing system constructed by the principle of the present invention shows unique and unambiguous conversion between syllables of English language and individual syllables of Korean language. No ambiguity is shown in the conversion process performed in the system. The syllables of English language are converted into a single unique syllable of Korean language without ambiguity. Moreover, each of syllables of English language converted into syllables of Korean language shows assurance of phonetic fidelity between pronunciation of syllables of English language and individual syllables of Korean language. Furthermore, since a unique and unambiguous correspondence between individual syllables of Korean language having Korean language vowels and Korean language consonants, and syllables of English language having English language vowels and English language consonants is implemented into the computerized romanizing system, the system is able to automatically convert between syllables of English language and individual syllables of Korean language with unambiguity and phonetic fidelity.

[0047] The system for romanizing the Korean language has the following features: A strict one-to-one relationship between individual syllables of Korean language having Korean language vowels and Korean language consonants and syllables of English language having English language vowels and English language consonants; One hundred percentage spelling accuracy for both romanization and reverse transliteration; Great accuracy of the pronunciation of personal and geographical names; the simplest womanization system of any foreign language. Even a non-Korean speaker who does not know how the word is pronounced or what it means can use the system by consulting the look-up table constructed according to the present invention.

[0048] The phonetic input method of this system is provided for standard English keyboard users, allows a Korean syllable to be generated in the computer memory and displayed on the computer screen by typing an English syllable that closely emulates the pronunciation of the Korean syllable to be produced, gives a transliteration table having the relationship between the English letters to be typed through the keyboard and the Korean characters to be produced on the screen, does not necessarily need a virtual keyboard displayed on the screen because of the phonetic equivalence between the English Key depressed and the Korean letter generated on the screen, and complete the creation of the Korean syllables corresponding to the typed English syllables by inputting a space key stroke.

[0049] In the machine translateration system, Korean syllables of Korean document stored in a Korean word processor are automatically converted into English syllables according to the look-up table of the memory. For example, a Korean name,

, is automatically transliterated into Gim Dae Joong. A space is created between Gim and Dae and between Dae and Joong. Since the individual syllables are separated from each other by a space, a Korean name,

, is romanized into Han A Reum rather than Hanareum and Ha Na Reum, and the input English syllables, Han A Reum, is transliterated into

. If there is one additional space between two Korean syllables, upon the transliteration, two spaces appear between the corresponding English syllables.
